We currently have plenty of Hyper Black, Anthracite, and Satin Black ARC-8's in stock for your E9x M3 that are ready to ship!

Here is an example of a beautiful E90 M3 with a 18x10.5" square setup and 295/30/18 Hankook Ventus TD tires. This is a very aggressive track setup that requires at least -3.8 degrees of front camber and a 5mm front spacer. Talk about going to the extreme for maximum grip on the track!

Please feel free to contact us regarding your street, track, or race application and we'd be happy to assist you!

Hi, i'm looking for a square setup for my 95 M3. i dont mind going with stretched tires. can you tell me what size I would need in a 18" ARC-8 hyper silver. (concave) Also what would my total be shipping to 33073.

The 18x9.5" ET35 can be used on your 95 E36 M3 with some work done to make it fit. The 18x9.5" ET35 ARC-8's are the most aggressive 18" wheel set up available for your E36 M3. Because of the wheel's concavity, it is most commonly used as a street fitment with undersized and stretched sidewall 245/35/18 street tires. The 18x9.5" ET35 with a 5mm wheel spacer is 6mm closer to the strut than the more common 18x9" ET42 with a 12mm wheel spacer. Even with the 5mm wheel spacer spring perch location with coilovers is very important. The required camber in front would be at least -3 degrees in conjunction with the 5mm wheel spacer. The rear fenders do need to be rolled but not pulled for this size, when in use with a 245/35/18 tire size. The area of contact is the worst where the rear bumper meets the fender so focus on that area with your fender roller the most. The rear camber should be maxed out, at least -2 degrees for it to avoid rubbing. Sending you a PM with a quote.

The 17x10" ET25 with a 275/40/17 will have the same issues as the 18x10" ET25 with a 275/35/18 does with KW's progressive V-shaped springs. With the KW Variants/ ST Coilovers, you would hit either the spring perch or the bottom of the spring itself with the V shaped springs, not the strut itself. In order to fix this issue with the 18x10" ET25 wheel clearance, you would want to use at least a 5mm spacer, or to switch to a linear spring. Because of the linear spring's shape, it is recommended to be used with camber plates. You may be able to source upper top hat that would work with the OEM upper mount.

The KW spring perch accepts a 60mm spring, thus you should look for a 6" 60mm spring from Swift, Hyperco, Eibach, or H&R. This will allow you to remove your V shaped spring and raise the lower spring perch higher.

With OEM suspension or coilovers with short linear race springs that keeps the spring perch above the wheel and tire, the 17x10" ET25 does fit without any issues.

Would 275/35/18 and 295/30/18 work with this setup? E92 with stock competition package suspension?

We have tested 275/35/18 and 295/30/18 Toyo R888 R-compound tires with our EC-7's in 18x10" ET25 and 18x11" ET25 with an e92 M3 that is lowered and it cleared without any issues in the past. If you are using a street tire, we don't see any issues with the OEM ZCP suspension using those tire sizes with the 18x9.5" ET22 and 18x10.5" ET27 ARC-8's.

Was not even aware of 18x11 size. Any pics of that setup (18x10 and 18x11)?

I have new set of Hankook 265/35/18 RS3 that I was going to run on a 18x9.5 wheel for the occasional track/mostly daily but NOW I want a set of Apex Arc8 18x10 et 25. I see that 275/35/18 is the ideal size tire but seeing if I could safely use the 265 on the track (Willow Springs). Granted I could get the 9.5" but I want the 10". Thanks...

The 265/35/18 can work on the 18x10" ET25 wheel, it is just a little undersized (by one size) and will have a little bit of tire stretch. You can safely run it on the track, it is just not ideal for the e9x M3 chassis. If you are only planning to use it temporarily, it wouldn't be an issue so that you can still make use of your current RS-3's.
